Role of aspirin in myocardial infarction. Dissolution of residual thrombus reduces luminal obstruction and may reduce the need for revascularization procedures since plaque disruption most often occurs in arteries with minor obstruction. After adjustment for differences between the treatment groups the use of aspirin was associated with 22 lower odds of 30-day mortality. The increased use of aspirin for patients with acute myocardial infarction is an excellent opportunity to improve the delivery of care to elderly patients.
Just as importantly clinical trials have also strongly suggested that the early administration of aspirin can substantially reduce the size of the myocardial infarction or convert a heart attack to unstable angina or convert an ST-segment elevation myocardial infarction STEMI to a non-ST segment elevation myocardial infarction NSTEMI. Role of Aspirin with Thrombolytic Therapy in Acute Myocardial Infarction Charles H. Thrombolytic therapy has been shown to limit infarct size improve ventricular function and decrease mortality in suspected evolving myocardial infarction MI.
Aspirin therapy also decreases mortality as well as stroke and. Chesebro JH Badimon JJ Hassinger NL. Acute myocardial infarction and the role of aspirin heparin and Warfarin.
J Thromb Thrombol 1 231235 1995. Days for myocardial infarction was reduced by 49. It is to be noted that the reduction in mortality with aspirin did not achieve statistical significance in any of these trials.
As mentioned earlier variations in the study protocol as well as in the entry window after myocardial infarction I week to 5 years may have affected the statistical significance of the results.

Myocardial Infarctiondrug therapy Substances. Clinical trials have demonstrated a prophylactic role for aspirin in myocardial infarction and in unstable angina pectoris. The Swedish Angina Pectoris Aspirin Trial SAPAT is the first prospective study of aspirin in stable angina.

El-Hadidy Hazem F. 18 September 2014 The Authors 2014. Role of Aspirin with Thrombolytic Therapy in Acute Myocardial Infarction Thrombolytic therapy has been shown to limit infarct size improve ventricular function and decrease mortality in suspected evolving myocardial infarction MI.
Aspirin therapy also decreases mortality as well as stroke and reinfarction in suspected evolving MI. Aspirin is one of the most frequently used drugs worldwide and is generally considered effective for the secondary prevention of cardiovascular disease. By contrast the role of aspirin in primary prevention of cardiovascular disease is controversial.
Early trials evaluating aspirin for primary prevention done before the turn of the millennium suggested reductions in myocardial infarction. Conversely prevention of ST segment elevation myocardial infarction through aspirin use was consistent in diabetic individuals who were concomitantly affected by hypertension and hypercholesterolemia. Aspirin or another oral antiplatelet drug is protective in most types of patient at increased risk of occlusive vascular events including those with an acute myocardial infarction or ischaemic stroke unstable or stable angina previous myocardial infarction stroke or cerebral ischaemia peripheral arterial disease or atrial fibrillation.
Conclusions Aspirin has been shown to be beneficial after a myocardial infarction and for other acute coronary syndromes. However variances in the proportion of patients with suspected ischaemic heart disease given aspirin in different ambulance services indicates the need for a re-emphasis on the importance of this treatment. Aspirins inhibitory effects on platelet func- tion provided the rationale to examine its utility in preventing myocardial infarction.
Seven pla- cebo-controlled trials of aspirin in the secondary prevention of myocardial infarction have been completed 2 3 8151628 36. Also in a recent study done by Yamasaki et al. It was found that low doses of both aspirin and clopidogrel led to reduction of PTX3 and high-sensitivity CRP levels at the very early onset of myocardial infarction MI with ST-segment elevation and the investigators stated that PTX3 could more directly reflect vascular inflammatory status than high-sensitivity CRP.
